- Operates from -20 °F to 400 °F across heating and cooling systems
Copper reducing tee for plumbing installs
The Nibco 611R is a wrot copper reducing tee designed for drain and trap assemblies. Its C x C x C solder connections join a 2-1/2 inch run to a 1 inch branch in residential or commercial pipework. The fitting meets ASME/ANSI B 16.22 standards for pressure service.
Rated pressure and temperature limits
Maximum working pressure is 336 psi at 100 degrees F, with a continuous operating range from -20 to 400 degrees F. The copper construction resists corrosion in hot and cold water systems while maintaining joint integrity across the full temperature span.
Replaces older brass or steel tees in retrofit work
The copper body eliminates dissimilar-metal corrosion when joined to existing copper pipe and reduces weight compared with threaded iron fittings. The jump is worthwhile when the system operates near the 336 psi rating or when soldered joints are preferred over threaded connections for leak resistance.

Questions about this item
How do I install the 2-1/2" x 2-1/2" x 1" wrot copper tee using the C x C x C connections?
Clean the 2-5/8 in and 1-1/8 in outside diameters, apply flux to each tube end, insert fully into the three cups, then solder the joints evenly; the step often missed is heating each cup uniformly so solder flows completely around the fitting without voids.
What maintenance or replacement will the wrot copper reducing tee need over time?
The copper body requires no scheduled maintenance; inspect joints periodically for green corrosion or leaks caused by thermal cycling between -20 and 400 Degrees F, and replace the tee only if a joint fails or the fitting shows pitting from aggressive water chemistry.
What limit appears first when the tee runs continuously at high pressure and temperature?
The 336 psi rating at 100 Degrees F is the primary design limit; sustained pressure above this value or temperatures approaching 400 Degrees F will degrade joint integrity before the copper material itself yields.
